The couple who met at a boat party last summer following Arquette's separation from wife Courteney Cox have apparently decided to give their relationship another go after splitting last month, reported Life and Style magazine.
"David and Christina are fully back together. They spend all their time together. They are totally boyfriend and girlfriend again. David is happy and he says he loves her," said a source.
"Yes, it's true. They are back together," added a second insider.
Arquette, 40, who has daughter Coco, seven, from his 11-year marriage to Courteney, went public with Christina last July when they appeared together at Comic Con.
"She's adorable. I'm not one to run around with different girls. I like someone that makes me feel good and that I can make feel good," said Arquette.
The actor-director is based in Los Angeles and Christina in New York, where she works as a reporter on 'Entertainment Tonight' and the distance was the reason of their split.
Announcing the split on twitter, David had earlier said, "Sadly I'm single again. A long distance relationship proved to be too difficult." PTI CORR
